TY - JOUR A1 - Wilke, Olaf A1 - Wiegner, Katharina A1 - Scheffer, Harald A1 - Brödner, Doris A1 - Kalus, Sabine T1 - Determination of the emissions of volatile organic compounds from oriented strand boards and evaluation by the German AgBB scheme N2 - There has been an increasing use of oriented strand boards (OSBs) for the construction of floors, ceilings and walls of buildings. In Germany and other European countries, OSBs are mainly produced from pine wood (Pinus sylvestris). In response to complaints about the odour and irritation of mucous membranes in connection with the use of OSBs, samples of OSBs were bought from do-it-yourself stores to test their volatile organic compound (VOC) emissions by using emission test chambers. The boards emitted predominantly monoterpenes, aldehydes, acids and acetone. Aldehydes are generated during the production process by the oxidation of unsaturated fatty acids such as linoleic acid. Pine wood, compared with other wood species, contains more unsaturated fatty acids. Of the six acquired OSBs, four boards from three manufacturers would not meet the requirements of the German AgBB (Ausschuss zur gesundheitlichen Bewertung von Bauprodukten, Committee for Health Evaluation of Building Products), mainly because of the emissions of unsaturated aldehydes. These compounds have low LCI values (lowest concentration of interest) and are therefore problematic substances based on a health-related evaluation of building products according to the AgBB scheme.

Unfortunately there is no method to validate the performance of such test chamber measurements. This might give a Variation of results when testing one material at different laboratories. Therefore it is necessary to hold round robin tests as part of the quality management System to ensure comparable results. A research project financed by the Federal Environmental Agency focused on the development of an external quality management System for the detection of relevant Chemical compounds from products and in ambient air. The project was structured in four phases (Horn et al., 2009 and 2011; Wilke et al., 2009a) This paper shows results of the fourth phase of the project, which was an inter-laboratory study for VOC-emission testing by means of emission test chambers.

Therefore Chemical emissions from wood have an influence on the indoor air quality. A research project financed by the Federal Environmental Agency focused on VOC emissions from oriented Strand boards (OSB) and also from plywood made from pine and spruce (Wilke et al., 2011a). This paper shows results of the plywood testing because only little information is available about plywood emission behaviour and its impact on indoor air quality.

T1 - Bestimmung der VOC-Emissionen aus Grobspanplatten (OSB-Platten) und ihre Bewertung nach dem AgBB-Schema N2 - In den letzten Jahren ist der Markt für Grobspanplatten (engl.: Oriented Strand Boards, OSB) zum Einsatz beim Hausbau gewachsen. Die Platten werden in Deutschland und Europa hauptsächlich aus Kiefernholz hergestellt und finden Verwendung in Bodenbelägen, Decken und Wänden. Durch ihren Einsatz kann es zu gesundheitlichen Beschwerden, wie Geruchsbelästigungen oder Schleimhautreizungen, kommen. Die Bundesanstalt für Materialforschung und -prüfung (BAM) hat im Auftrag des Umweltbundesamtes (UBA) ein Forschungsvorhaben zu Emissionen aus Holz und Holzwerkstoffen durchgeführt. In Emissionsprüfkammern wurden unter anderem Proben von sechs OSB-Platten aus Baumärkten untersucht und ihre VOC-Emissionen (engl.: Volatile Organic Compounds, VOC) gemessen. Vier dieser Platten von drei verschiedenen Herstellern würden die Anforderungen des Ausschusses zur gesundheitlichen Bewertung von Bauprodukten (AgBB) nicht einhalten. Größtes Problem hierbei sind die ungesättigten Aldehyde. Der Einsatz von Antioxidantien während der Produktion kann helfen, ungewollte Emissionen deutlich zu reduzieren.
